The amp clamp is designed to work on circuits measuring which frequency?

Explanation:
Amp clamps measure the changing magnetic field produced by current and are calibrated for the frequencies of typical power systems. Those systems run at the mains frequencies of 50 Hz or 60 Hz, so the device is specified as 50/60 Hz to cover both common standards. Using it at other frequencies isn’t as accurate because the sensing and internal circuitry are optimized for line frequency. That’s why the best answer is 50/60 Hz—it reflects the two main mains frequencies worldwide. Frequencies like 60 Hz alone leave out regions that use 50 Hz, while 20 Hz or 100 Hz are not standard for most power circuits, making readings less reliable.
